Best to worst:
Acura, Nissan, Cadillac, Volvo, Volkswagen, Saab
Acura: No-brainer. If you can afford it, this is heads above the rest!
Nissan: Isn't the Armada a mini-van? It can have some mechanicals, but Nissans are pretty good.
Cadillac: Unreliable, generic "luxury". The SRX is not the CTS. It's nothing special at all, in fact.
Volvo: Very safe! Iffy reliability, though.
Volkswagen: Over-priced, maintenance and repairs, also over-priced. Reliability? Over-rated.
Do NOT buy a Volkswagen.
Saab: You will(sob). A lot. Less reliable and less luxurious than the SRX listed above.
